I wanna to design a circuit to measurement the value of the Rload which is a resistive load.Here,I use the INA284 to measure the low current across the Rload and then use the voltage measurement circuit which deos not mentioned above to measure the voltage,Vload, acrossed the Rload.But AM3 which is 41nA does not equal to AM1 which is 35.5uA.We know that Rload=Vload/I.Here is my question: which current should I choose?AM3 or AM1.
My English is not good enough so if there have some grammatical mistakes.I wanna to say sorry.
Best regards,
Hugo
